Platform Architecture Documentation

This directory contains comprehensive architecture diagrams and documentation for the CMPDR Risk Management & Position Sizing Platform.

Overview​

The platform is a Node.js/Express backend with a static HTML frontend that supports multiple providers: TopStepX (REST + SignalR) and cTrader (FIX quote + REST bars + execution). Strategy instances are bound to one provider; risk engine and execution adapters are resolved per instance via the provider registry.
